Özet

Bis-N,N'(salicylidene)-2,20-dimethyl-1,3-propanediamine (LDMH2) has a high tendency to form polynuclear complexes. Two trinuclear complexes were obtained using this ligand and azide ions; (CuLDM)2 . Mn(N 3)2 . (DMF)2, [(C19H 20N2O2Cu)2 . Mn(N3) 2 . (C3H7 NO)2] and (CuLDM) 2 . Cd(N3)2 . (DMF)2, [(C 19H20N2O2 Cu)2 . Cd(N3)2 . (C3H7NO)2]. The structures were identified with X-ray methods. TG and DSC methods were also employed to these complexes. Studies showed the (CuLDM) 2 . Mn(N 3)2 . (DMF)2 and (CuLDM)2 . Cd(N3)2 . (DMF)2 to be non-linear. Also μ-bridges were not encountered for the azide ions but were seen to form between the Cu and other metal via phenolic oxygens. Thermal analysis showed exothermic degradation of the azide ions destroying the trinuclear structure. Although azide containing structures show explosive characteristics, this was not observed for the present compounds. © Akadémiai Kiadó, Budapest, Hungary 2009.
